MK 251 76 G

Headers, Male Pins Overview

The MK 251 76 G is a precision male pin header manufactured by Fischer Elektronik, designed for reliable rectangular PCB connections. It features a 0.5 mm diameter solder and plug pin with a 0.100 inch (2.54 mm) pitch. This connector offers 76 positions in a dual-row configuration, suitable for through-hole mounting. The contacts are gold-plated to ensure durability and low resistance. Rated for 1.5 A at 60 VDC, it operates within a temperature range of -40°C to 163°C, meeting UL94 V-0 flammability standards.

Headers, Male Pins Feature Summary

• Precision-engineered 0.5 mm diameter pins for secure board-to-board or wire-to-board connections
• Dual-row layout providing 76 contact positions with standard 2.54 mm spacing
• Gold-plated contacts ensuring high conductivity and corrosion resistance
• Through-hole termination method for robust mechanical stability on printed circuit boards

Headers, Male Pins Applications

• High-density electronic assemblies requiring precise signal routing
• Industrial control systems utilizing rectangular PCB interconnects
• Test and measurement equipment needing durable connection points
• Automotive electronics modules demanding reliable thermal and electrical performance

Headers, Male Pins Procurement Notes

Verify the specific suffix 'G' corresponds to the required gold plating thickness and packaging format as defined in the official Fischer Elektronik datasheet. Confirm that the 76-position count matches the design footprint requirements. Ensure compatibility with mating female headers from the same series to maintain alignment and contact integrity during assembly processes.

Headers, Male Pins Selection Notes

Select this component when a dual-row header with exactly 76 positions is required for through-hole applications. Consider the 0.5 mm pin diameter for space-constrained designs where standard 0.64 mm pins may not fit. Evaluate the 1.5 A current rating against the total load distribution across all rows. Verify that the operating temperature range meets the environmental conditions of the final assembly.

Headers, Male Pins Part Context

The MK 251 series represents Fischer Elektronik's line of precision male headers characterized by their 0.5 mm pin diameter. This specific model, MK 251 76 G, belongs to the broader family of rectangular connectors designed for high-reliability applications. The series emphasizes consistent contact geometry and durable materials, catering to industries requiring stable electrical connections over extended operational lifetimes.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Fischer Elektronik MK 251 variants with different pin counts, such as MK 251 68 G or MK 251 48 G, provided the row count and pitch remain identical. Cross-brand replacements must match the 2.54 mm pitch, dual-row configuration, and through-hole termination style to ensure physical and electrical compatibility.
